Interest on the National Debt Just Hit a Record $1.36 Trillion
The federal government just logged a debt-service bill so large it dwarfs the entire budgets of most countries, yet the bond market shrugged it off. Here is what that disconnect reveals about the hidden pressure building under long Treasury prices.
Treasury’s full-year count for fiscal 2026, released October 16, 2026, shows a record $1.36 trillion in debt-service spending for the year ended September 30, 2026.
That figure is gross, so it includes interest credited to federal trust funds such as Social Security. In other words, part of it is money the government pays itself. The Committee for a Responsible Federal Budget puts net interest paid to outside holders at $1.1 trillion, a record 3.4% of GDP. The CRFB also projects that annual deficits could reach $3.1 trillion by 2036 if nothing changes.
A government paying record interest has to keep selling long-dated debt. That supply weighs on exactly what the iShares 20+ Year Treasury Bond ETF (NASDAQ:TLT) holds.
Yet TLT barely moved. It closed at $80.05 on October 16, up 0.1%, and gained 2.65% over the week as investors again moved money into long bonds during a tech selloff.
Spending Outran a Record Tax Haul in Fiscal 2026
The deficit reached $1.99 trillion, up $217 billion, or 12%, from $1.78 trillion in fiscal 2025. That made it the largest deficit in five years, rising to 6.2% of GDP from 5.8%.
Receipts hit a record $5.40 trillion, up from $5.24 trillion. But spending rose faster, to a record $7.40 trillion from $7.01 trillion.
Tariffs did little to close the gap. Net tariff income fell 11% to about $173 billion after $145 billion in refunds, and September swung to a $27 billion deficit from a $198 billion surplus a year earlier.
Borrowing covered the shortfall. Gross national debt stands at $40,329,229,827,541.02 in Treasury’s latest Debt to the Penny reading.
How Record Borrowing Hits Long Treasury Prices
Bigger deficits mean more Treasury issuance. When buyers have to take on more long bonds, they demand extra yield for tying up their money for decades, which is called the term premium, and higher long yields push TLT’s price down.
Duration measures how much a bond’s price moves when rates change. Funds holding 20- to 30-year bonds move much more for each change in yields than short-term funds do.
Long Treasuries have lost money throughout the debt build-up. TLT is down 4.95% in 2026, 8.29% over one year, 33.99% over five years, and 19.72% over ten years, near the low end of its 52-week range of $76.43 to $92.19.
Why Long Bonds Still Have Defenders
Starting yields help. The 20-year Treasury yielded 5.47% and the 30-year 5.43% on October 16, the highest points on the yield curve. Both were down from 5.67% and 5.63% on October 2.
A recession or Fed rate cuts would pull long yields lower and lift TLT’s price. In the meantime, monthly distributions, most recently $0.311581 a share, provide income for holders.
The bear case is regular supply, sticky inflation, and worry that deficits will pressure the Fed, which set its target upper bound at 4.00% in September 2026. The budget watchdog also warned that “the country’s future fiscal outlook is even more dismal.”
What Record Deficits Mean for TLT Holders
TLT likely faces continued pressure, which matters most for income investors near retirement. Record deficits mean heavy long-bond supply for years to come, and the fund has lost ground throughout the build-up. A bad period in the first years of retirement does more lasting damage than a bad period later, which is the whole subject of our free guide on defending those early years.
Short-duration Treasury funds, which hold bills and notes maturing within a few years, carry less of that risk. The 1-year Treasury yielded 4.46% and the 2-year 4.74% on October 16, so those funds give up some yield but carry much less exposure to the supply of long-dated debt.
Two price levels will show whether this view holds. A TLT close below $76.43 would confirm that supply is winning. A close above $92.19 would mean a recession or Fed cuts have outweighed the deficit, and the view was wrong.
